POLE-PROTECTING DEVICE.

Application filed July 11,

My invention relates to improvements in pole protecting devices whichare particuarly adapted for use on wooden telegraph and other poles,fence posts and the like.

I have found that the rot usually suffered by a pole is greater adjacentthe surface of the ground than it is at the lower extremity, and thatthe disintegration results particularly from a soil condition wherehumidity W and dryness alternate. At the foot of a ploe I have usuallyfound that the humidity of the soil is substantially constant and. inconsequence little or no rot appears.

The objects of the invention are to provide means whereby that portionof a pole which is embedded in the ground is prevented from rotting,such as usually occurs and which weakens the base of the pole andreduces its effective life, involving the replacement of the pole withits attendant expense.

The invention consists essentially of a wrapping of the base of the polewith a material capable of permitting a flow of air therethrough, animpervious covering for the wrapping, and means for preventing theseepage ofrain or surface water about the covered portion of the polebase, as will be more fully shown in the accompanying drawings anddescribed in the following specification, in which Fig. 1 is a sectionalview of the ground showing the base of a pole therein and the inventionapplied thereto.

Fig. 2 is a general view of the invention as fitted to a pole erected ina sidewalk.

In the drawings like characters of reference indicate correspondingparts in each figure.

The numeral 1 indicates generally the ground into which a' hole 2 is dugfor the reception of a pole 3. If the pole is a large one requiring arelatively long embedded portion, I encircle its foot, from above theground line 4 to a point above its lower extremity with a wrapping ofheavy. galvanized wire mesh 5 or other suitable material of an opentexture. Surrounding the wrapping'5 is an impervious coating 6 such gavanized iron or other like material against which the soil returned tothe hole after the insertion of the pole is tamped.

The coating 6 is preferably carried up 1927'. Serial No. 204,921.

above the ground line 4 and the wrapping 5. above the groun coating 6 isa cone shaped flashing 7 which terminates sllq'htl above the round hne 4z, y D

and serves to deliver rain water flowing down the pole at an appreciabledistance therefrom,

so that seepage in intim base of the pole or the It will be obviou atecontact with the coating 6 is prevented. s that manymodlfications whichwould engage the circulating passages, mg within the scope o Byproviding flashing 7 and pole and provide air such modifications bef theinvention.

an annular space between the the groun d line 4 air is permitted to passfreely around the base of the pole to stimulate from below the groundalso circulate between the pol an evaporation of moisture The air ma e 3and the level.

impervious coating 6 through the interstices of the wrapping 5 ducedwhereby the foot so that a condition is proof the pole is moist due toits direct contact with the ground, such moisture content throughoutthat portion covered.

being gradually reduced ofthepole which is This gradually diminishingmoisture content is considered to remain substan tially constant withthe result that I have found poles so treated to be in perfectly goodcondition when others, not so equipped, but

in exactly similar to be dangerous an It will thus be seen th poleprotector which is form and in application,

ground, were so rotted as d require replacement.

at I have invented a extremely simple in and which will greatly increasethe effective life of the post to which it is fitted.

What I claim as my invention is: 1. Pole protecting means comprisingaretlculate matcrlal wrapped around a portion of the pole that is groundand an outer ering surrounding said reticul ate material,

the interstices of the reticulate material serving to permit circulationof pole and the outer covering.

2. Pole protecting means wrapping of reticulate portion of the pole thatair between the comprising a material covering a is adapted to beemslightly above Snugly fitted about the pole d line and also above theto be embedded in the imperforate metal covbedded in the ground, anouter imperforate metal covering surrounding said wrapping, theinterstices of the wrapping serving to permit circulation of air betweenthe pole 5 and the outer metal covering and an annular inclined shieldsecured to the pole and having its lower edge projecting below the upperend of said outer metal covering so as to prevent the entrance of rainbetween the pole and said outer covering While permitting the en 10trance of air.

Dated at Vancouver, B. C., this 22nd day of June, 1927.
